Application led September 4, 1924. l Serial No. 735,785.

To all whom it may concern: Be it known that I, GEORGE D. FULL, a citizen of the United States, residing at Waukegan, inv the county of Lake and State of-Illinois, have invented certain new and useful Improvements in Locks, of which the following is a specification. Y

'This invention relates to improvements in a type of combination or permutation locks for swinging or hinged doors, particularly those of buildings, but not re'- stricted thereto in its use, and consists in the novel construction, arrangement and combination of the various parts thereof, as vwill be hereinafter more fully set forthA and specifically claimed.

An object of the invention is, to provide a lock of the above mentioned general character which shall be comparatively simple in construction, with its parts so made, arranged and co-operating with one another and with the door knobs that it maybe manipulated to throw it into a locked or iinlocked position, and also, that it may be used as an ordinary latch.

Another object is to provide means in a combination lock for readily changing the permutation or combination thereof Whenever deemed advisable.

Other objects and advantages of the invention will be disclosed in the following description and explanation, which will be more readily understood when read in conjunction with the accompanying drawings, in which an embodiment of the invention is illustrated, it being understood that changes and modifications may be resorted to without a departure from the spirit of the invention so long as they come within the scope of the appended claims forming a part hereof.

ln the drawings,-

Y

Corresponding numerals of reference refer. to like parts throughout the different views ofthe drawings.

The reference numeral 10 designates a portion of one side of a. door frame which is equipped with a recess or socket 11, in its edge adjacent the door 12 for the reception of the latch or locking bolt 13 of the lock when the same is projected for leither locking or latching the door. Located in a mortise 14 of any suitable size and shape with which the door 12 is provided in its portion adjacent the frame is the lock casing 15, which is by preference rectangular in shape as shown and has on vthe inner surface of its rear wall 16 near its top and bottom a pair of apertured or socketed bosses 17, which apertures are by preference screw-threaded to engage screws not shown, employed for securing'the front wall or face plate 18 of the lockl casing in position, which latter plate will rest on the front ends of the bosses 'or studs 17 as is clearly shown in Fig. 3 of the drawings. The rear plate 16 is provided about midway between its top and bottom with a circular opening 19 for the reception and operation of the inner end of the knob spindle designated as a whole by the numeral 20 for the front knob 21 of the door or that knob which is located outwardly of the door. This opening 19 is also employed to receive and hold one end of a sleeve 22 which extends from the rear wall 16 of the casing to the front wall 18 thereof and is fitted within an opening 23 therein,

its opening 19 with a segmental -slotlland just below said opening with another simi-V lar slot 25 for the reception and operation of a pair of projections26 arranged in spaced relation to one another-on' the inner face of the Ihollow head2? of the knob. spinf dle Sfoi `A the rear knob29 or that one 1ocated pnfthe inner surface of the door` These projectionsQ are employedlfor the purpose of engaging a .pafujof openings 29a infanv arnr w ich .a1-in is pivotally :connecited near its outer end'to the rear surface otoneof theprongs 3l of the latch orlocking bol 13, which as isclearly shown inig. 2 of the drawings, is substantially. lil-shaped when lviewed in yfront'elevaltion and hassaid plio'ngs vsc spaced and located als to slid'ably rest against :thestnds lfllon opposite 's1des thereof and also' so arranged as to stride the Wai/h will beareinf referred@ wahutinterferen'ce therewith. The Jar x n 30 as i s'clear1y sliown in Fig. i 7,4 is provided wardly of its pivot 32 with a dislr-lilrez largement 33 whichl has a ,entral opening for the reception of the sleeve 22 and ijs"pro vided with the openings 29a at diametrically opposite points with respect to said central opening for the reception otthev projection 2G carried by the head or enlargement 27 of the knob spindle 2S to which ,theknobw29 may be detachably secured by means of a screw 34 seated in a portion of said knob and engaging said spindle.- The arm 30 yis also provided in its disk portion 33 with a recess 35 for the purpose to be presently eX- plained.

Uniting the rear and front plates 16 and 18 respectively of the locking casing are a pair of studs 36 which are diametrically spaced with respect to the sleeve 22 and are employed for the purpose of holding a pairl of washers and spacing rings interposed between certain elements of the locking mechanisin against rotary movement. The casing 15 is provided on the inner surface. of its inner side wall with a pair of spaced studs 37 for the support of a pair of spiral springs 33 each of which springs surrounds at one of its ends one of said studs and rests at its other end against thc inner end of one of the prongs 31 of the latch or locking bolt which is designated as a whole by the referencenumeral 13 as before indicated. This latch or locking bolt is provided midway between its prongs 31 with a guide-way 39 for a plunger 40 which has its inner portion reduced as at 41 for the purpose of engag- 1 g certain recesses in the tumblers and spacing rings as will be hereinafter explained. The plunger 40 has on its front surfacea projection or pin 42 for cri-operation with a slot 43 in p'late designated jas a' lwhole by the'n'neral 44, the construction of which is clearly shown in Fig. 2 of the drawings.

The plate" 44'Y is 'provided with an upward entension 45 which has a curved recess 46 'o engage a pin or projection 47 carried by the'upper prongl of the latch or locking bolt and extended forwardly from said prong, and said plate isprovided with an opening 48 toreceive the frontportion oi the sleeve .22, which sleeve 'is provided with diametrically disposed recesses 49 which extend from its front end vto near therniddIe of the sleeve as is clearly shown in FigsQ 2 and 3 of thezdrrawings. These recesses are adapted to register with recesses o() arranged l diametri'cally with respect: to the opening 48 in the plate 44-and are empoyed for the/pui'x o selo' engaging projections 'luwhich are lgiainetrically disposed on 4spind l`,e ..2Qf. under .oertaln vmovemeiifs r;onditfsf infile.. It. V211 oo ,obserred refenceto li'g. i2 4tha'tfthe Slet 43 in the' plate 44 is diagomuydisposed inla lateral extension52pf saidl plate and 9') that. said slot 'I isA offlilfilit A'cani lformation.

Mounted betweenftie )studs l36 and between the* arm-30land plate 44 are a number. ofV v'el'eilnents of the lock which will now be described. On the front surface o1" the member 30 a thin metal .washer yt3 -surrounding the sleeve'22 is nounted in er.- gagernent with the, "sti 1ds,36 so as to prevent it turning, and this washer hasa recess 54 in its periphery registeringr with the recess 35 in the disk portion 33 of vthe arm 30 but of sinaller dimensions or rathero less width than the last named recess. Mounted onfthe front surface of the washer and rotatably surrounding the sleeve 22 is a disk tumbler 55 Awhich has a recess 5G in its periphery to register with the recess 54 ol saidwas'her.

Located on the front surface of the tumbler 55 is a spacing ring 60 which is of' larger diameterv than said tumbler and enV gages at its periphery the studs 3G between which it is located to prevent its rotaryY movement. The ring 6() is of a broken type and has its ends spaced to forni a reces.c Gl". to register with the recesses 56, 54 and 3:7 of the just above named element.

Mounted on the front surface of the ring 60 so as to turn on the sleeve 22 is another tumbler 62 which has a recess 63 in its periphery to register with the recess 6l of the ring' 60. Mounted on the front .surface ofthe tumbler 62 is a spacing ringv G4 ot the same size and construction as the ringl 60 and mounted in a like manner. The n" cess 65 of the ring 64 is adapted to ister with the previously namedL recesses. Mounted on the 'front surface of the ring 64 is theI vfront or outermost tumbler which is adapted for rotary movement on the sleeve 22 and has in its periphery a recess 67 adapted for registration with the other recesses. This tumbler 66 has a centrally disposed key-way 67l for the projections 51 on the spindle 20.` V.The rear tumbler 55 is rovided on its frontsiurface with a projection such as a small sfrew 68 and the intermediate tumbler 62 is provided on each of itsl side surfaces with a similar projection 68 while the frontv tumbler is provided o n its rear surface with a similar projection to engage the. projection 68 von the front surface of the intermediate tumbler. These projections are' arranged so that they will travel in the same Acircle so that when it is desiredto set the combination ofthe lock they-will impinge oneV another when the tumblers are turned in the proper directions. l

Between the front` tumbler .and the plate 44 is interposed a thin metal washer 69 of the same construction las the washer 53 and mounted -in the same Way. As will beuseen in Figs. and 5, the front knob spindle 20 has its extreme rear portion` re-. duced and provided ,with an ,annular'flange 70` at its rear end, `and that this reduced portion is located in the cavity of the head 27 of the rear knob spindle 28.. To afford a swivel connect-ion between the spindles 20 and 27 the head 28 of the last named spindle is provided witha screw-threaded,opening 71 for the reception of a screw v72 which is extended through the cavity of the head 27 so as to permit locking movement of either ol' the spindles and also so as to restrict the longitudinal movement of the .front spindle 20, for it is apparent that the fiange 7() on the rear end of said spindle will restrict its forward movement.

lt will be seen that the spindle 20 is cylindrieally enlarged as at 73` which enlarged portion rests at its inner end when the parts of the lock are in the positions shown in the various views of the drawings, so as to permit retraction of the latch or bolt, on the front surface of the front plate 18 of the lock casing, it being understood that said cylindrically enlarged portion is extended through an enlarged opening in the front surface of the door.

Outwardly of the enlarged part 73 the spindle 20 is reduced as at 74, see Fig. 5, and has detachably secured on said reduced portion by n'ieaus of a screw 75, the front knob 21; which screw is extended through a suitable opening in a portion of said knob and is seated or engages the reduced portion 74 of the said spindle. Between the portion of the knob 21 which surrounds the reduced portion 74 and the outer end of the enlargement 73 is mounted for rotation a milled disk 76 which has in its surface adjacent the enlargei'nent 73 a pair of diauieri-z'ally disposed concared recesses 77 and 78 for co-operation with the outer end of a springaetuated bolt 79, which bolt as well as its-spring, is located in a longitudinally disposed opening 80 near the periphery of the enlarged part 73 as is clearly shown in Fig. 5 of the drawings, in which view it will be observed thatv the recess 77 in which the outer head of the bolt 79 is located, is deeper than the recess 78 and that when the parts of the lock are in the positions shown in the various views of the drawings, the inner end of the bolt 79 will rest against the outer surface 'of the front plate 18 of the lock casing.

The cylindrical part 73 is provided with a longitudinally disposed key seat 81 for co-operation with a key or projection 82 with which the dial plate 83 is provided at the e e of its central opening' through which t e enlargement 73 of the spindle 20 is extended. The dial plate 83 is protected by a centrally =oriiced"housing 84 which is mounted on and secured to the front face of the vdoor by means of screws or otherwise, and said housing carries an apertured glass plate 85 near its front portion through which the .graduated scale of the dial plate may beseen. The front face of the housing 84 is provided with an index 86, see Fig. l, to be used when the dial is turned for setting the combination of the lock in the well knownpway. l i

From the foregoing and by reference to the drawings, it will be readily understood and clearly seen that when the parts are arranged as shown in Figs. 2 to 5 inclusive, the bolt or latch 13 may be operated as a latch from either side of the door by turning the knob 21 or the knob 29 in the proper direction, for it is apparent that as the plunger 40 ei'igaging through its projection 42 and slot 43 the extension 52 of the plate 44, will occupy about the position shown by dotted lines in Fig. 2 or so that its reduced portion 41 will not be in engagement with the recesses of the tuniblers but in proper position to be forced into such engagement by tui-nin the plate 44 by means of the knob 21 and its spindle to the right. In this operation the projections 51 on the spindle 20 will engage the recesses 50 i'n the plate 44 thus permitting it to be turned so that the bearing or recess 46 in the extension 45 of said plate will co--operate with the projection 47 on one of the prongs 31 of the latch to retract the same,

ln order to prevent the tulnblers heilig accidentally turned by the inward and rotary movementot' the spindle20 and its projections 51, the turning member or disk 76 may be turned from the position it. occupies as shown in Fig. 5 to such position that the shallow recess will receive the rounded end of the spring pressed bolt 79, it being understood that by turning the member 7G the bolt 79 will be forced inwardly from the recess 77 so that its outer cnd will ride on the inner face of the member 76 until it reaches the shallow recess 78, in which it will be seated, thus causing its inner end acting against the outer surface of` the front Wall 18 of the casing to force the entire spindle 20 outwardly so that the parts will assume about the positions shown by dot-ted lines in Fig. 3, in which positions the projections 51 on the spindle will be held in engagement with the recesses 50 of the lat'e` 44 and free from engagement with t e front or outermost tumbler. It is appljet that the screw or member 72 Contacting with the i'lange 70 on the inner end of the spindle 20 will restrict the outward movement of said spindle. it will be understood that the bolt 13 can be operated as aV latch at all times by means of the' knob 29 and its connections with the arm 30 by simply turning the knob 29 in the proper direction to actua'te said 'arm against the prong 31 in a direction against the tension of the springs 38 which serve to hold the latch 13 in its normal position.

' In order lto set the tumblers in combination without removing the lock from the door, should the combination be accidentally disarranged, for instance, by one not familiar with the operation of the lock, the rear plate 1G of the'casing is provided between the opening 19 therein for the spindle 20 and sleeve 22 and the outer side wall of the casing at a point over the inner'end of the tongue or reduced portion 41 of the plunger 40 and over the peripheries of the tumblers, with an opening 19a, see Fig. 6, which registers with an opening 87 in the rear surface of the door at a point between the rear spindle 28 and the free edge of the door, as shown in Fig. 4 of the drawin s. By this arrangement it is manifest that by removing the knob 29 the plate 88 used for ornament and secured to the door can be removed so that the manipulation of the. tumblers caused by the rotary movement of the spindle 20 can be seen through the registering openings 87 and 19=l to the end that the combination can be easily effected.
